really needs to work better in Firefox for Android. refuses to remove the "open in app" floating button or floating Whatsapp icon from at least Times of India.

Helps not always, but quite often to remove a lot of annoying floating foregrounds of all kinds.

Works like magic!

Great idea. But I tried many sites, and this add-on was never able to remove one single pop-up. Ctrl-Shift-X had no effect whatsoever.

uBlock Origin's annoyances filter list sorts out most sites, otherwise you can use the uBlock Origin zapper

Excellent, does what it promise but, sadly, only on desktop. Can you make it work in Firefox for Android on a mobile? I use Nightly with a custom addon collection, and the problem is that it doesn't seem to have a toolbar, so I cannot tap the icon or press the keyboard shortcut, this being a phone.

Works like a charm!
